We reported last month that Sugarland will perform on the show, and now we know that the song the four-time CMA award-winners be singing is actually not one from any of their albums. Instead, the superstar duo have invited former tourmate Matt Nathanson to join them on stage to sing a song they all wrote together, 'Run,' which is on the multi-platinum selling pop singer's latest album, 'Modern Love.'

Jason Aldean, Brad Paisley, Blake Shelton and Taylor Swift lead this year's CMA pack with five nominations apiece. Read our predictions on the winners here. Hosted by 'Remind Me' duet partners Brad and Carrie (who will perform that song together on the show), the 45th Annual CMA Awards air live from Nashville, Nov. 9 at 8:00 PM ET on ABC.
